One historic sitcom device has been on the way out for years now, but the cancelation of this major show may be the final nail in the coffin.

Are there any comedy shows that are recorded before a live audience still airing?

Isn't a laugh track a cue system for those listening to know when a punch/funny line was said?

I often have TV shows playing in the background when working on something else. If I am not closely paying attention, I sometimes will back up the show (if streaming or watching a DVD) to hear the joke.
